NETWORK INTERFACE DEVICE, APPARATUS, AND METHODS
BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates generally to a network interface
'device
used in a telecommunications network, and more specifically, to a universal
network
interface device capable of accommodating conventional line modules and
protectors
and including independent subscriber and telecommunications service provider
access. More generally, the present invention relates to telecommunications
and,
more particularly, to equipment useful at subscriber demarcation points.
Technical Background
[0002] Telephone service is provided by a telephone company ("provider")
to
a number of different customers of the provider, commonly referred to as
"subscribers." Each subscriber may purchase as many separate telephone lines
as
desired and equip his or her home or business with various types of telephone
equipment. Subscribers are responsible for proper operation of the telephone
equipment and the provider is responsible for proper operation of the
telephone
network up to the interface between the provider wiring and the subscriber
wiring.
[0003] Therefore, it is desirable to provide a telephone network
interface
device ("NID") to serve as a demarcation point between the provider wiring and
the
subscriber wiring. NIDs serve the function of isolating the provider portion
of the
system or wiring from that of the. respective subscribers. Such isolation is
desirable in
1

CA 02635754 2008-06-27
WO 2007/079074 PCT/US2006/049256
order to segregate the responsibility for faults or malfunctions that may
occur in the
respective parts of the system.
[0004] In practice, known NID designs are typically mounted to an
exterior
wall of a house or building. Conventional NIDs generally include a container
or
housing, the interior of which is divided into a provider portion and a
subscriber
portion. Provider wiring typically enters the NID and terminates in the
provider
portion. The provider portion also typically contains protective devices to
protect
equipment and users from excess voltages. The subscriber wiring typically
enters the
NID and terminates in the subscriber portion. At least one interconnect
apparatus is
located between the two portions and generally operates to connect the
subscriber
wiring to the provider wiring.
[0005] Outer covers are typically provided for the respective housing
portions
that permit only provider access to the provider portion of the housing and
both
provider and subscriber access to the subscriber portion thereof. In such
housings of
the prior art, the covers are pivotally mounted to the housing.
Disadvantageously, in
such housings of the prior art, a provider technician attempting to gain
access to the
terminating equipment and wiring of the provider portion, must perform a two
step
procedure: first opening the subscriber portion and second opening the
provider
portion. Only by performing this two-step procedure can full access be
obtained.
Accordingly, one aspect of the invention requires improvements that provide a
one
step overriding access feature to the provider portions of the NID.
=
10006] The housing of known NID designs typically includes at least one
routing means for routing provider and subscriber lines into the interior of
the MD.
These routing means generally include an entry port having a conventional
grommet
2

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
disposed therein. The grommet is typically provided with a punch = out pattern

allowing a provider technician to punch out a portion of the grommet and
insert a
provider or subscriber line. However, the use of conventional grommet designs
suffer
the disadvantage of having at least a portion of the grommet tear off during
insertion.
With a portion of the grommet torn off, an effective seal against
environmental
contaminants is no longer provided.
[0007] As used herein, the term "interconnect apparatus" or "terminating
device- is intended to include any type of known connector for interconnecting

service provider wiring with subscriber wiring, configured with or without a
protection element for protecting against a voltage and/or current surge,
including but
not limited to a line module, a protected terminating device ("PTD"), or the
like.
[0008] Known interconnect apparatus are typically a modular device that
can
be mounted in the subscriber portion of the NID and easily replaced if
rendered
inoperable. Prior art terminating devices, such as line modules, typically
include a
housing and a cover that can pivot between a closed position and an open
position.
The housing of the line module includes a pair of insertion channels that
allow the
provider wires to be electrically .coupled with a pair of contacts located in
an
integrated jack. The jack is typically a conventional RJ-1 I jack. The cover
may be
connected to the line module by a hinge so that the cover can be rotated away
from
the housing of the line module to permit access to the jack. As mentioned, the
jack
has a pair of contacts that are electrically coupled to the tip and ring
wires.
[0009] Likewise, the plug attached to the cover has a complementary pair
of
conductors that make contact with the jack contacts when the plug is engaged
in the
jack. The subscriber wires are connected to a pair of terminals provided on a
portion
3

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
of the line module known as the bridge. The plug conductors are also
electrically
coupled to the terminals. Thus, when the cover is closed, an electric circuit
is
completed between the provider wires and the subscriber wires. When the cover
is
opened, the subscriber wires are disconnected from the provider wires.
However, a
test plug can be plugged into the jack to determine if the provider wires up
to the line
module are conducting properly. The bridge is removable, and thus, replaceable
if
rendered inoperable. However, the line module may also be provided with a non-
removable bridge. Existing and known interconnecting apparatus suffer the
disadvantage of not being capable of being employed in various NID designs. As

such, it is desired for an improved interconnect apparatus that is capable of
=
deployment in various NID types.
= [0010] Accordingly, there is a specific and unresolved need
for a low cost
universal network interface device having advantageous features including a
protective outer cover having an integrated override feature operable for
permitting a
provider technician to gain access to provider portions and/or subscriber
portions of a
NID in one step. There is also an additional need for an improved sealing
structure at
the cable entry points on the NID, thus providing improved sealing around
provider or
subscriber lines entering the interior of the NID through a defined entry
port. Further,
there is a need in the art for a universal network interface device capable of

accommodating conventional line modules and protectors of various types and
sizes,
and particularly for accommodating an improved line module having a looking
mechanism for preventing unauthorized access to the electrical connections
housed
within the terminating device.

SUMMARY OF THE INVENTION
[0011] In one aspect, the present invention is directed to a universal
network
interface device containing comprehensive modifications directed to
improvements in
the design, fabrication and utilization of such equipment. The network
interface
device generally includes a base and a protective outer cover movably attached

thereto. The base is preferably manufactured from a low cost ABS or PVC
material
having desired properties and the outer cover is preferably manufactured from
a PBT
material that meets and/or exceeds existing network equipment-building system
(NEB S) requirements.
[00121 In another aspect, the base of the MD generally defines an
interior
cavity for receiving the terminating equipment and wiring connections. The
interior
cavity is further defined by a provider portion and a subscriber portion. The
base
includes a perimeter wall which has at least one recess formed therein to form
at least
one entry port. Each entry port is configured to permit provider and/or
subscriber
lines to be routed into the NID. The entry ports are preferably provided with
a sealing
means or grommet :to prevent contaminants, such as moisture, dirt, dust, and
infestations, from entering the NID when the entry port is not in use or when
a
provider or subscriber line is utilized that is smaller in diameter than the
entry port.
[0013] The NID further includes a partition having an inner cover
forming
part thereof and an opening forming the remainder. The inner cover is sized to

correspond to and positioned over the provider portion of the NID. The opening
is
sized to correspond to and positioned over the subscriber portion. The
partition is
configured to be releasably secured and movably attached to the base of the
NID
between a closed position and an opened position by a locking screw that
requires an

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
industry specific tool to remove it. Accordingly, in the closed position, the
inner
cover of the partition prevents unauthorized access to the provider portion of
the NID.
The partition may be attached to the base by a series of hinges located along
one side
of the base and the partition, thereby causing the partition to pivot about
the hinges
between the closed position and the opened position. In the open position,
access to
the provider portion is provided. Since the partition is releasably secured to
the base,
the inner cover shields the provider portion from unauthorized access, while
permitting access to the subscriber portion.
[0014] The partition and the protective outer cover are preferably
provided
with a subscriber access means having a locked and an unlocked position
located
opposite the hinges at a desired location for locking the outer cover to the
partition. A
locking feature operable for receiving a combination or key lock (not shown)
belonging to the subscriber may also be provided. The locking feature may be
recessed within the NID such that it is less conspicuous. The subscriber
access means
permits the subscriber to gain access to the terminating equipment and wiring
connections contained within the interior subscriber portion when necessary or

desired by actuating the subscriber access means to an unlocked position and
manipulating the outer cover into the open position and accessing the
subscriber
portion through the opening.
[0015] The NID is also preferably provided with a provider override
means
for securing the partition and the outer cover to the base in the closed
position or
opening the NID in its entirety, thereby exposing both the provider portion
and
subscriber portion. The provider override means is configured to pass through
the
= outer cover and the partition and be fastened directly to the base. In
the open position,
6

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
the partition and the outer cover remain locked together by the subscriber
access
means. Accordingly, the provider override means permits a provider technician
from
the communications service provider to by-pass the subscriber access means and
the
locking feature, and thereby gain access to the interior contents of the NID
in one
step.
[0016] In yet another aspect, the present invention is directed to a
universal
NID including a novel sealing mechanism. The sealing mechanism is preferably a

grommet made of an elestomeric material and generally includes a grommet
holder
for securing the grommet in place within an entry port of the NID. The grommet

holder includes a pair of generally cylindrical guide posts for slidable
engagement
with a channel defined by the entry port of the MD. Preferably, the grommet is

provided with at least one grommet port operable for receiving at least one
provider or
subscriber line and routing the same into the interior of the MD. The grommet
port
includes a punch out pattern for insertion of lines from the provider or the
subscriber's
equipment. More preferably, however, the grommet is provided with at least one

grommet port having a flexible wave like shape such that the grommet port
stretches
when a line from the provider or subscriber equipment is inserted and
thereafter
sealingly surrounds the line.
[0017] In yet another aspect, the present invention is directed to a
network
interface device capable of accommodating a variety of terminating devices,
including
an improved terminating device or line module for interconnecting provider
lines with
subscriber lines including a locking feature. The improved terminating device
generally includes a base and a customer bridge mounted on the base, and is
typically
connected to a stuffer assembly. Generally, the customer bridge includes a
base and a
7

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
cover that is hingeably attached to the base. The cover of the customer bridge
is
equipped with a locking feature. The locking feature includes a locking slide
that
cooperates with a movable latch. The latch includes an upper portion, a lower
portion
and has a concave recess for cooperating with a subscriber lock. The upper
portion of
the latch is adapted to be captured by a notch of the locking slide and the
lower
portion of the latch is adapted to be captured by a catch of the base, thereby
locking
the cover to the base. In order to open the cover, a subscriber will have to
remove the
subscriber lock and manipulate the latch such that the notch and catch no
longer
capture the upper and lower portions of the latch. Alternatively, the locking
slide will
have to be slid into an open position, thereby allowing the latch to be moved
such that
the notch and catch no longer capture the relevant portions.
[0018] For added security, a wall of the inner cover of the NID is
configured
to overlie closely and abut the locking slide, thereby preventing substantial
lateral
movement of the locking slide and keeping the cover in the closed position.
Thus,
when in the closed position, only the removal of the subscriber lock will
permit the
cover of the customer bridge to be opened. When the inner cover is no longer
positioned to have the wall overlie and closely abut the locking slide, the
cover may
be opened with the locking arm of the subscriber lock captured within the
latch by
sliding the locking slide to the open position and moving the latch such that
the lower
portion is no longer captured by the catch of the base. In the event that an
unauthorized person forces open the cover of the line module, the lower
portion of the
latch and the locking slide will be broken off leaving a visual indication of
tampering.
[00191 In other aspects and alternative embodiments, the outer cover of
the
network interface device may include two sections, a provider cover and a
subscriber

cover. The provider cover and the subscriber cover are movably connected to
each
other by hidden hinges, such that the subscriber cover pivots about the
provider cover
into an open position, thereby exposing the subscriber portion of the MD.
Further,
the provider cover may be movably attached to the base by a series of hinges
located
along one side of the base and the provider cover. The provider cover is
defined by
the size of the provider portion and is preferably configured to fit closely
about the
base.
[0020] The subscriber cover is movably attached to the provider cover
and is
defined by the size of the subscriber portion. The subscriber cover is
provided with a
subscriber access means having a locked and an unlocked position. The
subscriber
access means is locked in the closed position to the provider cover, thereby
forming a
closed outer cover. The subscriber access means is configured to permit the
subscriber to gain access to the interior of the subscriber portion of the NID
only.
[0021] The MD may also be provided with a provider override means
opposite the hinges for securing the provider cover to the base in the closed
position
or opening the MD in its entirety thereby exposing both the provider portion
and
subscriber portion. The provider override means is preferably configured to
pass
through the provider cover to the base. More preferably, the provider override
means
is operable for unlocking both the subscriber cover and the provider cover in
one step.
In the open position, the subscriber cover and the provider cover remain
locked
together by the subscriber access means.
[0022] In another aspect a Network Interface Device (NID) component is
provided. The component includes a base configured to receive, in a cavity,
both a
subscriber wire contact and a provider wire contact, and a cover in movable

DETAILED DESCRIPTION OF THE INVENTION
[0080] Reference will now be made in detail to several exemplary
embodiments of the invention, and examples of which are illustrated in the
accompanying drawings. Whenever possible, the same reference numerals will be
used throughout the drawings to refer to the same or like parts. Various
embodiments
of a universal network interface device are shown throughout the figures and
are
designated generally by reference number 10.
[0081] Throughout this description, positional terms, such as left,
right, top,
bottom, front, rear, side, etc., and relative terms, such as larger, smaller,
nearer,
farther, etc., are utilized herein for purposes of explanation only, and as
such, should
not be construed as limiting the scope of the invention or the appended claims
in any
manner. In the embodiments shown, the universal network interface device 10 is

capable of accommodating various examples of line modules and protectors now
known or hereafter devised. The network interface devices shown and described
herein are particularly well suited for installations in which restricted
access to
terminating equipment and wiring connections belonging to the provider is
desired.
[0082] The present invention provides a universal network interface
device
(hereinafter referred to as a "NID") of the type commonly used in
communications
networks. The NID 10 acts a housing for a demarcation point between the wiring
of a
communication service provider (hereinafter "provider") and the wiring of a
subscriber's equipment. Since the NID 10 acts as a housing for a demarcation
point,
it is preferred that the device also provide a means for permitting access to
provider
17

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
portions of the NID 10 only or subscriber portions and provider portions of
the wiring
within the housing.
[0083] Further, it is preferred that the NID 10 include an integrated
override
feature operable for permitting the provider to access its wiring and
equipment
directly. Still further, it is preferred that the NID 10 include an improved
sealing
means for preventing environmental contaminants from entering the interior of
the
NID 10. Still further, it is preferred that the NID 10 be configured and
adapted to
receive various terminating devices including an improved terminating device
having
a locking mechanism operable for preventing unauthorized access to the
terminating
device's electrical connections or wiring.
[0084] Referring now to Figures 1, and 5-7, a NID is shown and indicated
generally at 10, and is constructed in accordance with one aspect of the
invention.
The NM 10 includes a base 12 that is generally rectangular in shape and a
corresponding protective outer cover 14 that is movably attached to the base
12,
thereby forming a closure. The base 12 and the outer cover 14 may be
manufactured
from any relatively rigid material, such as sheet metal, but preferably are
made of a
molded plastic, such as acrylonitrile butadiene styrene (ABS), polyvinyl
chloride
(PVC), polyethylene, polypropylene, polycarbonate, or polybutylene
terephthalate
(PBT).
[0085] More preferably, since the base 12 is affixed to the outside of a
building or the like it may be constructed from a low cost ABS- or PVC-type
material
having desired properties. Further, as the outer cover 14 is attached to the
base 12 and
is exposed to various stresses during operation, i.e. opening and closing, it
is
preferably constructed from a PBT-type material. The provision of using two
distinct
18

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
materials in the construction of the NID is such that an overall low cost
design is
provided while meeting and/or exceeding existing network equipment-building
system (NEBS) requirements set forth by Telcordia Technologies (Bellcore).
Specifically, the use of the PBT-type material for the outer cover 14 is
operable for
providing a greater tensile strength and a greater flexural strength to the MD
during
mold stress tests. By way of example, the outer cover 14 may be made of Valox

3706, a semi-crystalline, thermoplastic polyester resin based on PBT polymers
available from the General Electric Co., of Fairfield, Connecticut.
[0086] The base 12 of the NID 10 includes a back wall 21 (Figure 5) and
a
perimeter wall 20 depending upwardly along the periphery of the back wall 21.
Together, the back wall 21 and the perimeter wall 20 of the base 12 define an
interior
cavity 24 for receiving the terminating equipment and wiring connections
housed
within the NID 10. The interior cavity 24 of the MD 10 is further defined by a

provider portion 26 and a subscriber portion 28. The perimeter wall 20
preferably
extends upwardly from the back wall 21 and has a corresponding recess 23
formed at
the bottom thereof to form at least one entry port 30 (Figures 5-6).
[0087] Each entry port 30 is in communication with the interior cavity
24
defined by the base 12 to permit provider. and/or subscriber lines to be
routed into the
NID 10. The MD 10 may be provided with any convenient number of entry ports 30

operable for receiving any number of provider or subscriber lines. Preferably,

however, the NID 10 is provided with at least a first port for receiving a
provider line
from a communications network and a second port for receiving a subscriber
line
from a subscriber premises.
19

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
[0088] The entry ports 30 may be provided with a removable seal or cap
(not
shown). Preferably, however, the entry ports are provided with a sealing means
to
prevent contaminants, such as moisture, dirt, dust, and infestations, from
entering the
NID 10 when the entry port 30 is not in use or when a provider or subscriber
line is
utilized that is smaller in diameter than the entry port 30. Preferably, the
sealing
, means is a grommet 32. It will be understood by those skilled in the art
that the
grommet 32 is made from any suitable elastomeric material operable for
withstanding
environmental hazards, such as wind, rain, and/or snow.
[0089] As shown in Figures 8-9, the grommet 32 includes a grommet holder
34 for securing the grommet 32 in place within the entry port 30. The grommet
holder 34 includes a pair of generally cylindrical guide posts 36 for slidable

engagement with a channel (not shown) defined by the entry port 30 of the MD
10.
The guide posts 36 provide added security to the grommet 32 in the entry port
30
while lines from either the provider or subscriber are being inserted therein.

Preferably, the grommet 32 may be provided with at least one grommet port 38
operable for receiving at least one provider or subscriber line. It will be
understood
by those skilled in the art that any number of grommet ports 38 may be used
for
receiving any number of lines having various diameters.
[0090] By way of example only, Figures 8-9 illustrate a grommet 32
having
three grommet ports 38 operable for receiving either a provider or subscriber
line, or
both, of varying diameters. The grommet port 38 may include a punch out
pattern for
insertion of lines from the provider or the subscriber's equipment. More
preferably,
however, the grommet 32 is provided with at least one grommet port 38 having a

flexible wave-like configuration 40 such that the grommet port 38 stretches
when the

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
line from the provider or subscriber equipment is inserted. In operation, a
field
provider technician may cut or punch out a small diameter portion of the
grommet
port 38 and insert a line therethrough. As the line enters the interior cavity
24 of the
NID 10, the wave-like shape 40 of the grommet port 38 flexes or stretches and
sealingly surrounds the line, thereby preventing undesirable contaminants from

entering the NID 10.
[0091] When in use, the entry port 30 may also be sealed with a gel or
grease
around the line in a known manner to further prevent contaminants from
entering the
NID 10. As shown and described herein, a first port 30a for receiving a
provider line
is located adjacent a hinged side of the base 12 and outer cover 14, and a
second port
30b for receiving a subscriber line is located adjacent the side of the NID 10
opposite
the hinges 13. The first port 30a and the second port 30b, however, may be
located at
any convenient location relative to the interior cavity 24 of the NID 10. The
first port
30a and the second port 30b may also be combined into a single entry port 30
for
receiving both the provider lines and the subscriber lines.
[0092] Referring now to Figure 7, the base 12 may farther include one or
more feet 41 for mounting the NID 10 to a pole, wall or other building
structure at the
subscriber premises. Typically, the NID 10 is mounted outside the subscriber
premises and the outer cover 14 locked on the base 12, as described herein, to
prevent
unauthorized access to the terminating equipment and the wiring connections
housed
within the NID 10. Note that there are a plurality of mounts 41 such that NID
10 is
mountable to a variety of surfaces and in different orientations. For example,
the
mount 41 on top when looking at Figure 7 allows for using that mount and it
provides
a self centering of NID 10. Additionally, the mounts on the left and right
allow for
21

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
other mounting orientations. Further, there is another mount on the bottom and
as
shown in Figure 7, the NID 10 has a mount 41 on all four sides.
[0093] The outer cover 14 is movable between a closed position, as shown
in
Figure 1, and an opened position, as shown in Figures 5-6. The outer cover 14
includes a front wall 42 and a perimeter wall 44 that meets and forms a
closure with
the perimeter wall 20 of the base 12 to prevent moisture and elements from
entering.
As best shown in Figure 1, the front wall 42 of the outer cover 14 has a
generally
tapered configuration. However, as shown in Figure 2, it will be understood by
those
skilled in the art that the outer cover 14 may be constructed of a perimeter
wall 44 and
a smooth type front wall 42. In either case, the outer cover 14 may be movably

attached to the base 12 in any suitable manner, but preferably is attached to
a partition
52 by a series of hinges 13 located along one side of the base 12 and the
outer cover
14.
[00941 Accordingly, the outer cover 14 pivots about the hinges 13
between the
closed position and the opened position to provide access to the interior
cavity 24 of
the NID 10. As best shown in Figures 10-11, the base 12 may optionally be
provided
with hooks 15 and the outer cover 14 may be provided with snaps 16 that are
received
within the hooks 15 to secure the outer cover 14 on the partition 52 in the
closed
position. Also, the subscriber cover can be attached to and pivot from either
the base
or the provider cover.
[0095] As shown in Figure 5, the MD 10 further includes a partition 52
having an inner cover 54 forming part thereof and an opening 56 forming the
remainder. The inner cover 54 is sized to correspond to and positioned over
the
provider portion 26 of the termination equipment and the wiring connections
22

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
belonging to the provider that is housed within the interior cavity 24. The
opening 56
is sized to correspond to and positioned over the subscriber portion 28 having

termination equipment belonging to the subscriber such that either a provider
technician or the subscriber can access the termination equipment and wiring
within
the NID 10.
[0096) Further, the opening 56 is defined by a continuous rim 58 that
extends
from the inner cover 54 and runs coextensive with the edge of perimeter wall
20 of
the base 12. More preferably, the rim 58 is configured to accept a sealing
gasket on
either side thereof for preventing outside contaminants from entering the NID
10. As
stated hereinabove, the inner cover 54 of the partition 52 is defined by the
size of the
= provider portion 26 of the base 12 and is preferably configured to fit
closely within
the base 12 and outer cover 14. Further, the partition 52 is preferably
manufactured
of a low cost thermoplastic material and in preferred embodiments does not
need to
provide shielding against electromagnetic signals. However, it will be
understood by
those skilled in the art that the inner cover may be constructed to provide
such
protection.
[00971 The partition 52 is configured to be releasably secured and
movably
attached to the base 12 of the NID 10 between a closed position and an opened
position. For example, a locking screw that requires an industry specific tool
to
remove it may be utilized to releasably secure the partition 52 to the base
12.
Accordingly, in the closed position, the inner cover 54 of the partition 52
prevents
unauthorized access to the provider portion 26 of the terminating equipment
and the
wiring connections belonging to the service provider that is housed within the
interior
cavity 24 of the NID 10.
23

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
[0098] Furthermore, the partition 52 may be attached to the base 12 by a
series
of hinges 60 located along one side of the base 12 and the partition 52.
Accordingly,
the partition 52 pivots about the hinges 60 between the closed position and
the opened
position to provide access to the provider portion 26 and the subscriber
portion 28 of
the NID 10. In addition, access to the subscriber portion 28 of the
terminating
equipment and wiring connections belonging to the subscriber is not obstructed
by the
inner cover 54, when in the closed position, the subscriber can access the
wiring
through the opening 56.
[0099] Since the partition 52 is releasably secured to the base 12, the
inner
cover 54 shields the provider portion 26 from unauthorized access, while
permitting
access to the subscriber portion 28. The partition 52 and the outer cover 14
may be
provided with a subscriber access means 46 having a locked and an unlocked
position
and being located opposite the hinges 13 at a desired location along the rim
58 for
locking the outer cover 14 on the partition 52. Preferably, the subscriber
access
means 46 includes a locking screw (not shown) that requires an industry
specific tool
to remove it.
[00100] A locking feature 48 including aligned openings. through the
partition
52 and the outer cover 14 operable for receiving a combination or key lock
(not
shown) belonging to the subscriber may also be provided for additional
security. As
best shown in Figure 11, the locking feature 48 may be recessed within the NID
10
such that it is less conspicuous. The subscriber access means 46 permits the
subscriber to gain access to the terminating equipment and wiring connections
. contained within the interior subscriber portion 28 of the NM 10 when
necessary or
desired by actuating the subscriber access means 46 to an unlocked position
and
24

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
manipulating the outer cover 14 into the open position and accessing the
subscriber
portion 28 through the opening 56.
[00101] The NID 10 may also be provided with a provider override means
50
opposite the hinges 13 for securing the partition 52 and the outer cover 14 to
the base
= 12 in the closed position or opening the NID 10 in its entirety thereby
exposing both
the provider portion 26 and subscriber portion 28. Preferably, the provider
override
means 50 includes a locking screw (not shown) that requires an industry
specific tool
to remove it. However, it will be understood by those skilled in the art that
any
locking mechanism suitable for securing the outer cover 14, the partition 52
and the
base 12 may be employed.
[00102] The locking screw of the provider override means 50 is
preferably
configured to pass through the outer cover 14 and the partition 52 and be
fastened
directly to the base 12. In the open position, the partition 52 and the outer
cover 14
remain locked together by the subscriber access means 46. Accordingly, the
provider
override means 50 permits a provider technician from the communications
service
provider to by-pass the subscriber access means 46 and the locking feature 48
belonging to the subscriber, and thereby gain access to the terminating
equipment and
wire connections of the interior cavity 24 of the NID 10. Specifically, by
actuating
the provider override means 50, a provider technician may manipulate the outer
cover
14 and partition 52 to the open position thereby gaining access to both the
provider
portion 26 and subscriber portion 28 of the NID 10 when it is necessary to
service,
repair, or reconfigure the NID 10.
[00103] Unlike conventional NM designs, which require that the
subscriber
portion 28 be accessed independently from the provider portion 26, the use of
the

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
provider override means 50 provides a one step method of accessing the
provider
portion 26 and the subscriber portion 28 of the NID 10.
[00104] As referenced above, the NID 10 is capable of accommodating
various
interconnect apparatus. Further, the universal NID 10 disclosed herein may
also
include at least one improved terminating device for interconnecting provider
lines
with subscriber lines. An enlarged detail of a terminating device 100
constructed in
accordance with one aspect of the present invention is shown in Figures 12-15.
The
terminating device 100 may be any apparatus or device for interconnecting
provider
lines with subscriber lines, such as a subscriber line module ("SLM"),
protected
terminating device ("PTD"), or the like.
[00105] = For purposes of example only and not for limitation, the terminating

device shown and described herein is a line module 100 that is housed within
the NID
to serve as the demarcation point between the provider lines and the
subscriber
lines in the telecommunications network. The line module 100 generally
includes a
base 102 and a customer bridge 104 mounted on the base 102, and is typically
connected to a stuffer assembly 109. The customer bridge 104 is commonly
referred
to in the art as an interconnect module, a connector module, or a wiring
module. As
used herein, the term "customer bridge" is intended to include any apparatus
for
terminating wiring in a communications network, including but not limited to,
an
interconnect module, a connector module, a wiring module, or a customer
bridge.
[00106] Generally, the customer bridge 104 includes a cover 106 .that is
movable between a first, opened position and a second, closed position. The
cover
106 is provided with a plug that engages a jack formed on the upper surface of
the
base 102 when the cover is in the closed position. The jack includes test
contacts
26

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
disposed thereon that engage the contacts of an RI-11 plug of a conventional
telephone handset in a known manner to test for the presence of a telephone
"dial
tone" on the communications network. =
[00107] Since the NID 10 is typically mounted on an exterior wall of an
office,
apartment, commercial, or residential building, a home, or the like, the line
module
100 is susceptible to access by individuals that are not authorized to utilize
the
telephone service. As will be described in greater detail hereinafter, the
terminating
device of the invention deters the theft of telephone service by unauthorized
. individuals and protects the communications network and the subscriber's
equipment
from damage caused by excessive moisture, such as a flood condition.
[00108] The customer bridge 104 houses at least one insulation
displacement
contact ("IDC-) and a corresponding actuating arm for electrically connecting
the
subscriber wiring to the insulation displacement contact, and thus, to the
terminating
device. In operation, the actuating arm is placed in the "disconnect" position
and the
subscriber line is inserted into a wire insertion hole 124 of the
corresponding IDC.
The actuating arm is then moved from the "disconnect" position to the
"connect"
position to force the subscriber wiring into engagement with the IDC and
thereby
electrically connect the subscriber wiring to the customer bridge 104 of the
line
module 100.
[00109] Although the operation of only a single actuating arm, IDC and
wire
insertion hole 124 has been described herein, the customer bridge 104 may be
provided with any number of wire insertion holes 124, insulation displacement
contacts and corresponding actuating arms 120. As shown herein, the customer
bridge 104 has a plurality, and more specifically four, pairs of wire
insertion holes
=
27

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
124 and insulation displacement contacts, each pair corresponding to one of
the four
actuating arms 120. Accordingly, the customer bridge 104 may accommodate, for
example, up to four twisted pair tip and ring wires from various subscriber
telephone
equipment.
[00110] As one of ordinary skill in the art will readily understand and
appreciate, two or more conductive members are provided to electrically
connect the
insulation displacement contacts housed within the customer bridge 104 to
corresponding subscriber tip and ring conductors disposed within the jack 120
formed
in the base 102.
[00111] The base 102 is similarly provided with at least one insulation
displacement contact and is attached to the stuffer assembly 109 for
electrically
connecting the provider lines to the line module 100. As is well known, each
IDC has
a pair of opposed, sharp edges for piercing any insulation that may be present
on the
service provider wiring. The stuffer assembly 109 generally includes a
conventional
stuffer box 108 and securing screw 112 that cooperates to force the provider
lines into
engagement with the IDC. The stuffer box 108 is positioned for vertical
movement
on a post that is internally threaded for receiving the externally threaded
securing
screw 112. The stuffer box 108 further has at least one test port 111 formed
therein
for receiving a test clip to verify the integrity of the electrical connection
between the
provider wiring and the IDC.
[00112] In one aspect, the IDC is electrically connected to a protector
assembly. The protector assembly is in contact with a grounding box that
slides into a
portion of the stuffer assembly 109. The protector assembly is intended to
conduct
any over-voltages or current surges carried by the communications network to
the
28

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
grounding box as the grounding box is connected to earth ground upon
installation of
the NID 10. The terminating device including the protector assembly is
commonly
referred to as a "PTD", a protection device, or a protector.
1001131 In operation, the provider lines are inserted into horizontally
disposed
wire insertion passages formed in the staffer box 108 and though an opening
formed
in the upper portion of the IDC. The external threads of the securing screw
112
engage the internal threads of the post to drive the staffer box 108
downwardly
against the provider wiring positioned in the opening. As a result, the
provider lines
are brought into engagement with the opposed, sharp edges of the IDC, thereby
piercing any insulation surrounding the provider wiring and electrically
connecting
the provider wiring to the line module 100.
[00114] As one of ordinary skill in the art will readily understand and
appreciate, two conductive members are provided to electrically connect the
IDCs to
corresponding provider tip and ring conductors disposed within the jack formed
in the
base 102. Accordingly, the insulation displacement contacts housed within the
customer bridge 104 may be electrically connected to the IDCs by engaging the
subscriber conductors and service provider conductors disposed in the jack,
and
thereby selectively interconnect the provider wiring with the subscriber
wiring.
[00115] The cover 106 of the customer bridge 104 is also equipped with a
locking feature. The locking feature includes locking slide 110 that
cooperates with a
movable latch 128. The locking feature has a shape and size that is smaller
than
known locking mechanisms for line modules such that it may fit and be employed
in
various NID designs and configurations.
29

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
[00116] As shown in Figure 12, the latch 128 has a concave recess for
cooperating with a subscriber lock 300 (Figures 14-15). Figure 14 illustrates
the
interaction between the inner cover 54 of a conventional MD 10 and the line
module
100, and more specifically, the interaction between the inner cover 54 of the
MD 10,
the locking slide 110 of the line module 100, and the subscriber lock 300. The

subscriber lock 300 deters unauthorized access to the line module 100, while
permitting the subscriber and a provider technician from the provider to open
the
cover 106 of the line module 100 and. access the actuating arms that connect
and
disconnect the subscriber wiring with the insulation displacement contacts
housed
within the customer bridge 104.
[00117] The provider technician must still be able to open the cover 106
of the
line module 100 for purposes of testing the electrical connections between the

subscriber wiring and the customer bridge 104 even if dispatched when the
subscriber
is not at the customer site. As best shown in Figure 14, the perimeter wall 45
of the
inner cover 54 overlies and closely abuts the locking slide 110. The perimeter
wall 45
prevents substantial lateral movement of the locking slide 110. However, once
the
inner cover 54 is opened, the perimeter wall 45 no longer overlies and closely
abuts
the locking slide 110. Accordingly, the cover 106 may be opened with the
locking
arm 302 of the subscriber lock 300 captured within the latch 128.
[00118] The interaction between the perimeter wall 45 of the inner cover
54 of
the NID 10, the locking slide 110 and the cover 106 of the line module 100 is
illustrated in Figures 12-15. As discussed above, the locking arm 302 of a
subscriber
lock 300 may be captured within the concave recess of the latch 128. The latch
128
may then be positioned as shown in Figures 12 and 14.

[00119] In this position, the cover 106 cannot be opened because the
latch 128
has a lower portion 128b that is captured beneath a catch 130 of the base 102
and an
upper portion 128c that is captured beneath a notch 132 of the locking slide
110. In a
NID 10 servicing multiple subscribers at the same site, such as an apartment
or
commercial building, an unauthorized person may attempt to open the cover 106
of
the line module 100 to steal communications service. Once the cover 106 of the
line
module 100 is opened, the unauthorized person can insert the RI-11 plug of a
conventional telephone handset into the jack formed in the base 102 and
utilize the
communications service.
[00120] The subscriber lock 300 deters unauthorized use of the
communications service. In the event that an unauthorized person forces open
the
cover 106 of the line module 100, the lower portion 128b of the latch 128 and
the
locking slide 110 will be broken off The damage to the lower portion 128b of
the
latch 128 and the locking slide 110 provides a visual indication that an
unauthorized
person has attempted to gain access to the customer bridge 104 of the line
module
100.
[00121] If a provider technician dispatched by the service provider needs
to
gain access to the customer bridge 104 of the line module 100, he will be able
to open
the inner cover 54 using a special tool that is typically available only to
authorized
personnel. As shown in Figure 15, opening the inner cover 54 permits lateral
movement of the locking slide 110. After laterally moving the locking slide
110, the
upper portion 128c of the latch 128 is no longer overlapped by the notch 132.
Further, with the lateral movement of the locking slide 110, the subscriber
lock 300
may be removed and the latch 128 may be manipulated such that the lower
portion
31

CA 02635754 2008-06-27
WO 2007/079074 PCT/US2006/049256
128b is no longer overlapped by the catch 130 of the base 102. Accordingly,
the
cover 104 will no longer be locked to the base 102. The cover 104 can then be
opened.
[00122] Alternatively, the subscriber or a person authorized by the
subscriber
can remove the subscriber kick 300 and the latch 128 may be manipulated such
that
the lower portion 128b of the latch 128 is no longer overlapped by the catch
130.
Accordingly, by manipulating the latch 128, the cover 106 is no longer locked
to the
base 102. The cover 106 can then be opened even though the locking slide 110
is still
in the closed position.
[00123] As discussed above, the latch 128 is slidably captured by the
notch 132
and the catch 130 of the base 102. The catch 130 is preferably integrally
formed with
the base 102, and the locking slide 110 is preferably integrally formed with
the cover
106. The latch 128 further includes an upper surface 128a that is shaped and
dimensioned to engage a user's fingertip. As previously described, the latch
128 also
has a lower portion 128b. The lower portion 128b is relatively thin so as to
fit
comfortably beneath the catch 130.
[00124] The shape of the lower portion 128b provides sufficient surface
area to
ensure adequate contact with catch 130. Further, the attachment point between
the
lower portion 128b and the rest of the latch 128 is sufficiently small such
that the
lower portion 128b will snap off if an unauthorized person attempts to gain
access to .
=
the line module 100 by forcing open the cover 106. Damage to the lower portion

128b of the latch 128 provides a visual indication that an unauthorized person
has
attempted to gain access to the line module 100. The latch 128 also has an
upper
portion 128e.

PCT/US2006/049256
[00125] The upper portion 128c is relatively thin so as to fit
comfortably
beneath the notch 132. The shape of the upper portion 128c provides sufficient

surface area to ensure adequate contact with notch 132. Further, the
attachment point
between the upper portion 128c and the locking slide 110 is such that the
locking slide
110 will snap off if an unauthorized person attempts to gain access to the
line module
100 by forcing open the cover 106. Damage to the locking slide 110 provides an

additional visual indication that an unauthorized person has attempted to gain
access
to the line module 100.
[00126] Referring again to Figures 12-15, the stuffer box 108 of the
stuffer
assembly 109 is shown to the immediate left of the locking slide 110 and the
movable
latch 128. The stuffer assembly 109 is covered by the inner cover 54 when in
the
closed position. In operation, the stuffer box 108 must move from an extended,
or
disconnected, position to a retracted, or connected, position to engage the
service
provider wiring with the IDCs.
= [00127] In the disconnected position, the stuffer box 108 must
not interfere
with the locking slide 110 or the perimeter wall 45 of the inner cover 54. As
previously described, the securing screw 112 is used to move the stuffer box
108
between the disconnected and the connected positions. The perimeter wall 45 of
the
inner cover 54 rests slightly above the stuffer box 108. The stuffer box 108
may have
an angled surface to permit a provider technician dispatched by the service
provider to
insert the service provider wiring into the wire insertion passages 111.
[00128] Referring now to Figures 3-4, a NID is shown and indicated
generally
at 10, and is constructed in accordance with another aspect of the invention.
The NID
includes a base 12 that is generally rectangular in shape and a corresponding
33

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
protective outer cover 14 movably attached to the base 12, thereby forming a
closure.
The base 12 of the NID 10 includes a back wall 21 (Figure 5) and a perimeter
wall 20
depending upwardly along the periphery of the back wall 21. Together, the back
wall
21 and the perimeter wall 20 of the base 12 define an interior cavity 24 for
receiving
the terminating equipment and wiring connections housed within the NID 10.
[00129] The interior cavity 24 of the MD 10 is further defined by a
provider 26
portion and a subscriber portion 28. The perimeter wall 20 preferably extends
upwardly from the back wall 21 and has a corresponding recess 23 formed
therein to
form a plurality of entry ports 30 (Figure 5-6). As shown in Figure 7, the
base 12
further includes one or more feet 41 for mounting the NID 10 in a known manner
to a
pole, wall or other building structure at the subscriber premises. Typically,
the MD
is mounted outside the subscriber premises and the outer cover 14 locked on
the
base 12, as described herein, to prevent unauthorized access to the
terminating
equipment and the wiring connections housed within the NID 10.
[00130] The outer cover 14 is movable between a closed position, as shown
in
Figures 3-4, and an opened position. The outer cover 14 is preferably split
into two
distinct sections including a provider cover 200 and a subscriber cover 202.
In
preferred embodiments, the provider cover 200 and the subscriber cover 202 are

movably connected to each other by hidden hinges (not shown) located along
respective perimeter walls 208, 210.
[00131] Further, the provider cover 200 preferably has a front wall 204
that is
at least partially overlapped by a front wall 206 of the subscriber cover 202
in the
closed position. Also, in the closed position, the perimeter walls 208, 210 of
the
provider cover 200 and the subscriber cover 202 meet and form a closure with
the
34

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
perimeter wall 20 of the base 12 to prevent moisture and elements from
entering. As
stated herein above, the provider cover 200 and the subscriber cover 202 are
preferably attached by hidden hinges, such that the subscriber cover 202
pivots about
the provider cover 200 into an open position. However, it will be understood
by those
skilled in the art that any suitable attaching mechanism that allows pivotable

movement may be employed. As best shown in Figure 3, the front walls 204, 206,

when in the closed position, have a generally tapered configuration.
[001321 However, as shown in Figure 4, it will be understood by those
skilled
in the art that the front walls 204, 206, in the closed position, may form a
smooth
surface. In either case, the provider cover 200 may be movably attached to the
base
12 in any suitable manner, but preferably is attached to the base 12 by a
series of
hinges 13 located along one side of the base 12 and the provider cover 200.
Accordingly, the provider cover 200 pivots about the hinges 13 between the
closed
position and the opened position to provide access to the interior cavity 24
of the N1D
10. The provider cover 200 is generally defined by the size of the provider
portion 26
of the base 12 and is preferably configured to fit closely about the base 12.
The
provider cover 200 acts to shield the provider portion 26 from unauthorized
access,
while permitting access to the subscriber portion 28.
[001331 As stated hereinabove, the subscriber cover 202 is movably
attached to
the provider cover 200 and is defined by the size of the subscriber portion 28
of the
base 12. Preferably, the subscriber cover 202 is configured to fit closely
about the
subscriber portion 28 of the base 12. As with the provider cover 200, the
subscriber
cover 202 acts to shield the terminating equipment and wiring connections
within-the
subscriber portion 28 from unauthorized access. The subscriber cover 202 may
also

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
be provided with a subscriber access means 46 having a locked and an unlocked
position. Preferably, the subscriber access means 46 is locked in the closed
position
to the provider cover 200, thereby forming the closed outer cover 14.
[00134] More preferably, the subscriber access means 46 includes a locking
screw (not shown) that requires an industry specific tool to remove it. The
subscriber
access means 46 permits the subscriber to gain access to the terminating
equipment
and wiring connections contained within the interior subscriber portion 28 of
the NID
when necessary or desired by actuating the subscriber access means 46 to an
unlocked position and manipulating the subscriber cover into the open
position.
[00135] The NID 10 may also be provided with a provider override means 50
opposite the hinges 13 for securing the provider cover 200 to the base 12 in
the closed
position or opening the NID 10 in its entirety thereby exposing both the
provider
portion 26 and subscriber portion 28. Preferably, the provider override means
50
includes a locking screw (not shown) that requires an industry specific tool
to remove
it. The locking screw of the provider override means 50 is preferably
configured to
pass through the provider cover 200 to the base 12. Preferably, the provider
override
means 50 is operable for unlocking both the subscriber cover 202 and the
provider
cover 200. In the open position, the provider cover 200 and the subscriber
cover 202
remain locked together by the subscriber access means 46. Accordingly, the
provider
override means 50 permits a field technician from the communications service
provider to by-pass the subscriber access means 46 and thereby gain access to
the
terminating equipment and wire connections of the interior cavity 24 of the
NID 10.
[00136] Specifically, by actuating the provider override means 50, a
provider
technician may manipulate the provider cover 200 and subscriber cover 202 to
the
36

CA 02635754 2008-06-27
WO 2007/079074 PCT/US2006/049256
open position, thereby gaining access to both the provider portion 26 and
subscriber
portion 28 of the NID 10 when it is necessary to service, repair, or
reconfigure the
NID 10. Unlike conventional NID designs, which require that the subscriber
portion
28 be accessed independently from the provider portion 26, the use of the
provider
override means 50 provides a one step method of accessing the provider portion
26
and the subscriber portion 28 of the NID 10.
[001371 Figure 16 illustrates a method 402 of bypassing a jack 404 in a
Network Interface Device (NID) component such as a terminating device. The
.
terminating device can be a Subscriber Line Module (SLM), a PTD, or the like,
however for consistency and clarity, and not for reasons of limitation, the
terminating
device is hereinafter referred to as a SLM. During normal operations with a
cover of
the SLM closed, the jack 404 is not in electrical contact with a provider line
406, and
provider line 406 is connected to a subscriber line 408, and shown in part 16a
of
Figure 16. However, when the cover is in an open position, as better explained

below, the jack 404 is connected to the provider line 406 and the provider
line 406 is
disconnected from the subscriber line 408 as shown in part 16b of Figure 16.
[001381 Figure 17 illustrates a SLM 410 including a base 412 and a cover
414.
The base 412 includes a cavity 416 in which are positioned a provider line
contact
418 connected to the provider line 406 and a subscriber line contact 420
connected to
the subscriber line 408. Contacts 418 and 420 are in one embodiment, opposed
biased
contacts in that they are biased toward each other and apply pressure against
a
bridging contact 422 placed on a contact support 424 extending from cover 414
when
cover 414 is in a closed position as shown in Figure 17. A wire 426 is biased
toward
provider line contact 418. Wire 426 extends to a jack 404 (not shown in Figure
17).
37

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
[00139] When cover 414 is in the closed position as shown in Figure 17,
contact support 424 pushes wire 426 away from provider line contact 418 such
that
the jack is in a non-powered state. Contact support 424 is a non-conductive
material
and includes a non-conducting end 428. An environment sealant is typically
used to
protect the electrical components in cavity 416. For example, in one
embodiment, a
gel at least partially fills cavity 416.
[00140] Figure 18 illustrates that there are two wires 426 extending to a
jack
position 430 wherein one wire 426 is a ring wire and one wire 426 is a tip
wire. A
holder assembly 432 holds contact 420 in place. Note that there is a gap 434
between
contact 420 and holder assembly 432 which allows for compression of contact
420
when cover 414 is in the closed position. Contact 418 similarly compresses,
and
when cover 414 is opened both contacts 418 and 420 expand toward each other
and
thus form a pair of opposed biased contacts. In the embodiment shown in Figure
18
the wires extend under the contacts to a side, and then upwards before turning

downwards at an angle in jack 430.
[00141] Figure 19 illustrates cover 414 in an open position and
illustrates the
electrical connection between wire 426 and contact 418. Figure 19 also
illustrates that
there are actually two bridging contacts 422, one for the ring connection and
one for
the tip connection.
[00142] Figures 20 and 21 illustrate another embodiment of SLM 410
wherein
the electrical connections are similar to the SLM 410 illustrated in Figures
17-19 in
that the subscriber line contact 420 is electrically connected to the provider
line
contact-4.18 when the lid 414 is in the closed position (Figure 20) and the
contacts 418
and 420 are not electrically connected in the open position (Figure 21).
Additionally,
38

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
also similar to the SLM 410 in Figures 17-19, the SLM 410 in Figures 20 and 21

electrically connects the jack wire 426 to the provider line contact 418 only
in the
open position. In the closed position, wire 426 is isolated from provider line
contact
418. These connections and disconnections are accomplished with a rotating
member
444 including a lobed end 446, a cylindrical middle portion 448, and a cammed
end
450.
[00143] Similar to support 424, this embodiment includes an actuator 442
extending from cover 414. Actuator 442 includes an arcuate section 443 which
engages lobed end 446 such that rotating member 444 is rotated upon closing
and
opening cover 414. Actuator 442 and support 424 both make and break electrical

connections and are therefore also referred to herein as make and break
members, or
singularly, as a make and break member. As seen in Figure 21, when the cover
414
was opened, cammed end 450 was rotated and pushed contact 418 away from
contact
420 and breaking the electrical contact which was shown in Figure 20.
[00144] Additionally, cammed end 450 is sized such that besides breaking
the
electrical connection between the contacts 418 and 420, contact 418 is biased
against
wire 426 thus energizing the jack. Although Figures 20 and 21illustrate one
side of
the SLM 410, another set of contacts 418 and 420, and another wire 426 is on
the
back side of SLM 410 such that one side is for the ring connection and the
other side
is for the tip connection. When the open cover 414 in Figure 21 is lowered and

closed, as seen in Figure 20, rotating member 444 is rotated and contact 418
moves
away from wire 426 and contacts with contact 420.
[00145] Note that contact 418 is biased toward contact 420 and will touch
contact 420 when cammed end 450 is in the position shown in Figure 20. Also
note
39

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
that contacts 418 and 420 are positioned in an internal closed chamber 452
(Figures
20 and 21 do not show sidewalls as shown below, but the SLM 410 in Figures 20
and
21 do include sidewalls), and an environment sealant is typically used to
protect the
electrical components in cavity 452. For example, in one embodiment, a gel at
least
partially fills cavity 452. The cavity 416 in the earlier embodiment is opened
to the
environment when cover 414 is in the opened positioned, but the chamber 452 is

never opened to the environment.
[00146] Figure 22 illustrates .the SLM 410 with sidewalls 460 thus
closing
chambers 452 in Figures 20 and 21.
[00147] Figure 23 illustrates the SLM 410 in an open position wherein a
top
plate 462 is positioned on top of sidewalls 460. Openings 464 for contact
supports
424 to pass through are provided on top plate 462. Figure 23 also shows jack
404 in
base 412. Top plate 462 also has a plurality of openings 464 for a plurality
of
actuating arms 470 to pass through. Cover 414 is pivotably mounted to base
412.
[00148] Figure 24 illustrates SLM 410 with a plurality of actuating arms
470
including one arm in a disconnected position 472 and one arm in a connected
position
474. An insulation displacement connector (IDC) 476 extends from a service
provider portion 480 to a subscriber portion 482 of SLM 410. Each actuating
arm 470
includes an opening 478 to receive an IDC 476. In one embodiment, the opening
includes an angled and curved portion 484. The portion 484 being angled and
curved
serves to make the opening 478 smaller than it would be with a non-angled and
non-
curved portion.
[00149] This size reducing feature aids in the IDC 476 entering opening
478
and displacing insulation on a subscriber wire by limiting the amount of flex
or travel

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
the IDC 476 has in opening 478. Actuating arm 470 can also have a pivot
journal 488
that mates with a bearing surface on the SLM 410. Journal 488 allows for
actuating
arm 470 to be pivoted between the disconnected position 472 and the connected
position 474. Actuating arm 470 can also have a channel 473 and a hole 486
which
both allow for gel to flow through arm 470 to facilitate an easy positioning
of arm 470
in the disconnected position 472 and the connected position 474. A detent 477
is
positioned on arm 470 such that the detent 477 will click into a corresponding

structure on the SLM 410 to inform a user that arm 470 is in the connected
position
474.
[00150] Additionally, detent 477 helps maintain arm 470 in the connected
position. Also, in one embodiment, arm 470 includes a' gel retention extension
479
extending from a medial section 481 of arm 470. Gel retention extension 479
serves
to block gel below extension 479 from moving above extension 479. Extension
479
also serves to act as a positive stop to stop the pivotal motion when
extension 479
contacts top plate 462. Extension 479 is also useful for blocking the gel from
being
seen by a user and helps to protect the gel from the environment.
[00151] Figure 25 illustrates SLM 410 with arm 470 in the connected
position.
Note how the IDC 476 extends into an IDC channel 492 on arm 470. Also on arm
470 is a subscriber channel 490 for receiving a subscriber wire. Note in
Figure 25
channel 490 is angled obtusely with respect to IDC 476, while in Figure 24
channel
490 is angled acutely with respect to IDC 476. Also channel 490 includes a
conical
shaped wire guiding section 491 which aids a user in inserting a wire in
channel 490.
In use, a user inserts the subscriber wire (typically with insulation) into
channel 490
41

CA 02635754 2008-06-27
WO 2007/079074
PCT/US2006/049256
and rotates arm 470 to the connected position and IDC 476 displaces the
insulation on
the subscriber wire and makes electrical contact with the subscriber wire.
[00152] Put another way, a user inserts the subscriber wire into the
one piece
unitary arm 470 and the arm is rotated from an acute relationship with the IDC
476 to
an oblique relationship such that the subscriber wire engages the IDC 476 in a
rotating
= motion. Heretofore, the subscriber wire engaged an IDC using linear
motion.
Additionally, because the arms 470 pivot and receive the IDC in the connected
position, arms 470 are also herein referred to a pivoting insulation
displacement
connector holders. Also note in Figure 25 there is an empty space below arm
470 in
which electronics such as a printed circuit board (PCB) can be placed. The PCB
can
be a half ringer, an ADSL board, or a VDSL board, or the like.
[00153] Figure 26 illustrates one embodiment of IDC 476 having tapered
generally v shaped provider end 494 and a slot 496 extending therefrom. IDC
476
also has a widened shoulder region 498. Shoulder region 498 is typically where
IDC
476 is attached to SLM 410. A channel 500 extends from shoulder region toward
a
subscriber wire portion 502 of IDC 476. The subscriber wire portion 502
extends to a
generally v shaped subscriber end 504. A ramp 506 is positioned between the
subscriber wire portion 502 and the subscriber end 504 such that the
subscriber end
504 is less thick than the rest of the IDC 476. This decrease in thickness is
because
the subscriber wire is typically a smaller wire in diameter then the provider
wire. For
example, subscriber end 504 typically receives 24-18 gage wire, and provider
end 494
typically receives 20-24 gage wire.
[00154] Figure 27 illustrates the SLM 410 wherein some arms 470 are in
the
connected position 474 and some arms 470 are in the unconnected position 472.

Figure 27 illustrates the routing of two provider wires 520 from different
elevations of
the IDCs 476 to jack 404. A chamber 524 where wires 520 are connected to the
IDCs
476 is typically filled with a potting material to protect wires 520. In other
words,
IDCs 476 are positioned in SLM 410 in a factory, provider wires 520 are placed
in the
provider ends 494 of the IDCs 476, and then the potting material is applied in

chamber 524.
[001551 Chamber 524 is also referred to herein as a provider wire routing
area.
The subscriber wire ends 502 of IDCs 476 are covered with a gel in the factory
and,
later in the field, the subscriber wires are connected to the IDCs 476. SLM
410 also
includes, in one embodiment, a plurality of test probe openings 522 on top
plate 462.
[00156] Figure 28 illustrates a protector module 550 with a ground
adapter 552
removeably attached to a back side 554 of the module 550. Module 550 also has
a
first side 556 where adapter 552 can also be mounted. Alternatively adapter
552 can
be mounted to a second side 558 or a front side 560 of module. Ground adapter
552
typically slides onto a mounting tab 562. Back side 554 of module 550 includes
two
openings 564 to receive two subscriber wires, and front side 560 includes two
openings 566 to receive two provider wires.
[00157] Figure 29 illustrates an exploded view of module 550 including a
base
portion 570 and a middle base portion 572 which is typically ultrasonically
welded to
base 570 forming an interior chamber which holds a ground and gas tube
assembly
574. A nut 575 is positioned on top of middle base 572 and a screw 576 is used
to
position a stuffer 578 on middle base 572_ Of course, other fasteners besides
screws
and nuts may be used. Within stuffer 578 are positioned two IDCs 580 which
extend
to ground and gas tube assembly 574. Two test contacts 582 are positioned on
top of
43

PCT/US2006/049256
stuffer 578 and are connected to the IDCs 580. Screw 576 is used to move
stuffer 578
towards and away from middle base 572. IDCs 580 allow for the electrical
connections between different wires, leads, etc. and thus fall into the
category of
being a connector member wherein the term connection member includes non
insulation displacement connectors.
[00158] Figure 30 illustrates a cut away view of module 550 wherein a
chamber 588 which houses most of the IDCs 580 is typically filled with gel.
Figure
30 also shows an interior chamber 590 which holds a ground and gas tube
assembly
574. Because base 570 and middle base 572 are ultrasonically welded together,
chamber 590 is sealed from the environment, and gel is typically not present
in
chamber 590.
[00159] Figures 31 and 32 illustrate the connection between ground and
gas
tube assembly 574 and the IDCs 580. A gas tube lead 594 extends from a gas
tube
596 and into the IDC 580. As seen best in Figure 32 the ground and gas tube
assembly 574 includes a plurality of ground mounting tabs 562 allowing a user
to
select which side to place a ground adapted 552. Accordingly, module 550 is
versatile and can be used in many different configurations with other
electronic
devices. For use with a Protector Termination Device (PTD), module includes a
PTD
footprint ground sleeve 600, in one embodiment. Also, a gas tube assembly arm
598
can be riveted to the mounting tabs 562 for ruggedness in the field.
[00160] Figure 33 illustrates the openings 564 have a generally circular
top
portion 610 and a slotted bottom portion 612. Figure 33 also illustrates the
IDC 580
has a provider wire receiving section 614, a subscriber wire receiving section
616 and
a gas tube lead (or wire) receiving section 622. Subscriber wire receiving
section 616
=

is shaped similar to openings 564 in that section 616 also includes a
generally circular
shaped top section 618 and a slotted bottom section 620.
[00161] Figure 34 illustrates two strengthening features 630 on IDC 580
to add
strength to provider portion 614. Features 630 extend outward away from edges
of
IDC 580 and proceed to turn and then extend perpendicular to a main body 631
of
IDC 580. Also shown in Figure 34 are two bending tabs 632 which provide for
easy
control and insertion when inserting a subscriber wire in subscriber section
616. The
bending tabs 632 also provide for good holding of the inserted wire.
[00162] Figure 35 illustrates a gas tube lead contact area 636 on IDC 580
such
that contact is made between IDC 580 and the gas tube lead at four points 638.
Note
that IDC 580 provides for three distinct IDC connections in a linear fashion.
In other
words, the subscriber line, the provider line, and the gas tube line are all
in a straight
line enabling a smaller size device (e.g., the PLM 700 described below) than
heretofore. Typically subscriber section 616 receives 24-18 gage wire, and
provider
section 614 typically receives 20-24 gage wire. Therefore, it is advantageous
to
strengthen or stiffen provider section 614.
[00163] Figure 36 illustrates the IDC 580 with strength features 630 that
extend
from body 631 toward the edges of body 631. In one embodiment, strength
features
630 are stamped portions of mc 580 which are then bent to break the plane of
IDC
580 and add rigidity to the provider portion 616 of IDC 580.
[00164] Figure 37 illustrates the IDC 580 with strength features 630 that
extend
from body 631 between a centrally disposed slot 639 and the edges.

[00165] Figure 38 illustrates the IDC 580 with strength features 630 in
the
centrally disposed slot 640.
[00166] Figure 39 illustrates IDC 580 wherein the subscriber wire portion
616
includes a pair of oppositely extending members 640. When a subscriber wire in

inserted in portion 616 one member 640 deflects in the direction of arrow 642
while
the other member 640 deflects in the direction of arrow 644.
[00167] Figure 40 illustrates IDC 580 wherein the subscriber wire portion
616
includes a pair of opposed contact members 650 having a longitudinally
extending
slot 652 with an inner facing depression 654. A slot 656 is also positioned in
portion
616 on a side of members 650 opposite the generally circular opening 618.
[00168] Figure 41 illustrates IDC 580 wherein a slot 660 extends to the
generally circular opening 618, and a u shaped channel 662 is placed around
the slot
660.
[00169] Figure 42 illustrates SLM 410 in combination with module 550
forming a protected line module 700 (PLM) that fits the herein described 3-
line NID
10. Note that in Figure 5 line module 100 is the same as SLM 410. However,
Figure
also shows a SLM below line module 100, and the SLM is connected to a separate

protector module to the left of the SLM and line module 100.
[00170] Figure 43 illustrates the PLM 700 with an adapter 710 that
enables
PLM 700 to fit with an NI-2000 series PTD commercially available from Coming
Cable Systems LLC of Hickory NC, hereinafter "CCS". The adapter 710 includes a

rearwardly and downwardly extending connection section 720 which mates with

structure in the NI-2000 series PTD. The adapter 710 also includes a section
which
attaches to module 550 and allows for the storage of subscriber wire in
section 722.
[00171] Figure 44 illustrates SLM 410 with module 550 remotely coupled to
SLM 410 via subscriber wires 740. A SLM adapter 438 is mounted to a side of

CACill 9600 MD, a CAC 7900 MD, and a CAC 5000 MD, all commercially
available from CCS.
[001721 Figure 45 illustrates SLM 410 without module 550 remotely coupled
to
SLM 410. A SLM adapter 438 is mounted to a side of the SLM 410, and subscriber

wires 740 extend from adapter 738. The wires may or may not be connected to an

adapter or to a subscriber directly. The SLM 410 as shown in Figure 45 is
attachable
to the CAC 7600 NID, the CAC 9600 MD, the CAC 7900 MD, and the CAC
5000 MD, all commercially available from CCS. Adapter 738 has, in one
embodiment, a channel shaped member 800 and a mating member 802 such that
adapter 738 facilitates connecting SLM 410 to another device with
corresponding
structure, such as, for example, module 550.
[00173] Figure 46 illustrates SLM 410 in combination with module 550 and
locking slider 110. Note that in Figures 46-51, the SLM 410 does not use the
SLM
adapter 438 shown in Figures 44-45.
